CLARINET.

SPECIFICATION forming part of Letters Patent No. 570,647', dated November 3, 1896.

Application led November 6, 1895. Serial No. 568,120. (No model.)

.T0 all whom t may concern:

Be it known that I, Giosnrrn OLIvEEr, a citizen of the United States, residing at lVashington, in the District of Columbia, have invented certain new and useful Improvements in Olarinets and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the aecoinpanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in clarinets, but it is also applicable to flutes, hautboys, bassoons, iiageolets, or other similar instruments,

The objects of the invention are to produce an adjustable piece or pieces for changing the clarinets or like instruments from a high pitch to a low pitch; also, to produce a very simple device that can be easily transported and applied in place without other means; also, to regulate the tones of clarinets, itc. from high to low pitch. Furthermore, it requires no changes to be made in the instrument and can be applied to old as well as new systems.

A still further object is to produce a lining having the proper holes or apertures in it required for the instrument in which it is to be used and made of metal or other suitable material; also, that it will readily accommodate and adjust itself to any unevenness in the interior of the tubes out of which the instruments are made, and, iinally, that the material used shall be of a resonant nature to increase the tone.

My invention consists in the construction of certain details and the arrangement of parts,as will be more fully described hereinafter, and specifically pointed out in the claims, reference being had to the accompanying drawings and the letters thereon.

Like letters indicate similar parts in the different 'figures of the drawings, in which- Figure l represents a longitudinal section of a clarinet without the keys having my improvement attached. Figs. 2 to 7, inclusive, represent the lining-tube in separate pieces in their regular rotation on an enlarged scale.

In the drawings, A represents a tube with the mouthpiece for a clarinet without the usual keys and other requirements necessary to form a complete instrument. In the interior side of this tube is placed whatlterm the lining B, made of metal. It is composed of the pieces c and d for the upper part, with the mouthpiece D, the next piece e for the part E, after which come the pieces f and g for the parts F and G, and finally the lower piece 7L, which is of a slightly-tapering shape for the bottom part H. These pieces are cut longitudinally, as shown at a, so that they can be slightly compressed, when they are to be placed in position, and then are allowed to spring against the interior sides of the tube. The holes made in the diiferent pieces of the lining must be made to correspond with the openings in the tube itself, and this applies to all instruments, such as flutes, hautboys, &c. These pieces can be introduced very quickly and easily whenever it is desired to change the pitch of the instrument from a higher to a lower pitch, and ordinarily can be carried in a box or pocket.

The lining may be made of one or more pieces, as desired, although I prefer to make it out of several pieces on account of the facility of transportation, as well as the manufacture.

The lining can be made of sheet brass, steel, bellmetal, or any other suitable metal or material having a springy or expansible, as

well as of a resonant material, and that it will readily and easily accommodate itself to any unevenness in the interior of the tube whether it is made of wood, metal, or other material. The lining can be easily applied or removed by the hand without other appliances, although it must fit closely in the tube.

If desired, all the pieces of the lining may be provided with small flanges 2, as shown, to prevent the pieces from being pushed in too far, and they can also be withdrawn easier by them. In introducing them into the tube of the instrument they should be inserted in the direction indicated by the arrows.

A great feature of this invention is that instruments provided with my improved lining will not be atfectcd by the changes in temperature.

Having thus described my invention, what IOO I claim, and desire to seeure by Letters ,Pat-

ont, is-

I. A lining inserted in clarinets, ttc. provided with a longitudinal out, which forms a space when in place, and having the proper apertures, required for the instruments, and serving to change the tone from a high to a low pitch, as specified.

2. In musicalinstruments, suoli as elarinets and the like, a lining` made of resonant material, in one or more pieces, provided with a longitudinal out forming a space when in plaee, and having the proper apertures to correspond With those in the tube, required for said instruments, as set forth.

3. As a new article of manufacture, a removable and adjustable lining of resonant material, provided with proper apertures as required for the instrument, and having a longitudinal cut to form a space as and for the purpose specified.

l. An adjustable lining, having a longitudinal eut a and sprung in place and provided with proper apertures to correspond with those in the tube of the instrument, made ol light resonant material, and held in place by its own elasticity, as set forth.

5. An adjustable and removable lining for instruments made of resonant material, and provided with the proper apertures required, having a longitudinal cut to form a space between the adjacent edges, and sprung in its place by its own elasticity, as shown and specified.

In testimony whereof I ai'lix my signature in presence of two Witnesses.
